Twin Screws Are Twin Screw Superchargers Considered "roots" Type?
Looking at the rules for the Class and it gives max size for Roots and Centrifugal supercharges but makes no mention to twin screw type.

A roots blower has 2 rotors in the case, but I never heard it called a twin screw type.
Sized from 4-71 thru 16-71, 4 & 16 are rare and 16-71 is usually illegal for most class'.
They make a screw blower, it has a bigger case than a roots and it is also not legal for some class'. Hope I helped.
